Wow, this question has made it rounds to 2 or 3 forums already. Section 220.2(a) 2002 NEC®, or 220-2(a) 1999 NEC® and the first words, "Unless other voltages are specified ...". Read the original question again. I missed it the first time.

Who is permitted by the code to specify a voltage. Why couldn't someone specify 126 volts and install 14 duplex receptacles?
Scott, The 80% does not apply so the answer based on the 115 volts is 12, but I don't think that anyone has the right under the code to specify a voltage for this circuit. It is my opinon that the calculation should be based on 120 volts. Don

Roger, So if I specified a voltage of 126 and installed 14 duplex receptacles, the inspector would have to pass my installation? I'll say what I have posted on other forums. The question is bogus. The installer does not have the right to specify the voltage. Don
